Chemical Structure
Description
The occurrence of Diphenanthro[3,4-b:4',3'-d]thiophene is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diphenanthro[3,4-b:4',3'-d]thiophene (CAS 168784-35-8) is a high-purity analytical reference standard with the molecular formula C28H16S and a molecular weight of 384.49 g/mol.
The molecular framework of Diphenanthro[3,4-b:4',3'-d]thiophene (C28H16S) is characterized by sulfur-containing functionality, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
